KEYS: Make the system 'trusted' keyring viewable by userspace

2013-09-25T16:17:01Z

Give the root user the ability to read the system keyring and put read permission on the trusted keys added during boot. The latter is actually more theoretical than real for the moment as asymmetric keys do not currently provide a read operation. Signed-off-by: Mimi Zohar Signed-off-by: David Howells

KEYS: Add a 'trusted' flag and a 'trusted only' flag

2013-09-25T16:17:01Z

Add KEY_FLAG_TRUSTED to indicate that a key either comes from a trusted source or had a cryptographic signature chain that led back to a trusted key the kernel already possessed. Add KEY_FLAGS_TRUSTED_ONLY to indicate that a keyring will only accept links to keys marked with KEY_FLAGS_TRUSTED. Signed-off-by: David Howells Reviewed-by: Kees Cook

KEYS: Separate the kernel signature checking keyring from module signing

2013-09-25T16:17:01Z

Separate the kernel signature checking keyring from module signing so that it can be used by code other than the module-signing code. Signed-off-by: David Howells
